My strategy for people that need to reach me by voice involves a one step IVR on my own asterisk system. This IVR is linked to a DID that I give out for this purpose. It answers and has a voice greeting prompt that says something like "press five zero zero to be connected". If someone does that, x500 initiates a new outbound call to my actual number, preserving the calling party's caller ID.

This cuts down on 99% of your car's extended warranty and IRS scam calls.

Which provider allows this? Won't stir/shaken authentication requirements break it in a few years?

I am my own provider: incoming DIDs reside with a wholesale SIP trunking service. Outgoing SIP with the same provider, usually, though I have multiple possible routes. The asterisk system, I run myself. My outgoing caller ID (and my carrier's links to its upstreams such as bandwidth.com) are SHAKEN/STIR compliant.

This sounds fascinating and also completely over my head in terms of possibilities… is there a basic “getting started guide” you would recommend for someone who may not have the bandwidth to go all-in learning telephony from soup to bolts but would still like the benefits? :)

How do the calls actually get routed to your phone? Via SIP, or through your cell provider (ie. it dials your phone's phone number)? If everything is over SIP, then it makes sense that everything is SHAKEN/STIR compliant.

I called someone today and they appeared to be using a generic call screening service that offers exactly this feature - a computerized voice asks you to enter a random number to be connected.

I didn't even randomize mine, it's literally the same greeting every time and a fixed extension number. Just the fact that it exists as a roadblock to listen to, comprehend and put in some DTMF tones seems to stop 99% of the scam calls.

once stir/shaken is in place, won't the underlying problem go away?
